PERFORATlNG-MACHINE.

SPECIFICATION forming partof Letters Patent No. 516,199, dated March 13,1894. Application filed February 8, 1893. Serial No. 461,453- (Nomodel.)

To all whom it may concern.-

Be it known that I, JOHN K. GORE,a| citizen of the United States,residing at Newark, 1n the county of Essex, State of New Jersey,

have invented certain new and useful Improvements inPerforating-Machines; and I do declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which 11: appertains to make and use thesame.

My invention has for its object to materially increase the facility andrapidity with which cards or other papers or substances may beperforated, especially such cards as are used for actuarial purposes, inthe computation of life insurance matters, compilation of tables, the.

My invention relates to that class of machines in which the punches areoperated from akeyboard,and comprises an automatic feed for deliveringthe cards to be punched 1n proper position in front of the punches withthe minimum efiort of and without practical loss of time by theoperator.

With such ends in view my improvement consists in the novel parts andcombinations thereof hereinafter set forth.

In orderto make the invention more clearly understood I have shown inthe accompanylng drawings means for carrying the same into practicaleffect, without, however, limiting the improvement in its usefulapplications to the particular construction which, for the sake ofillustration, I have delineated.

In said drawings-Figure 1 is a vertical longitudinal sectional view online 1-1 Fig. 2, of a perforating machine embodying my invention. Fig. 2is a top plan view of the same. Fig. 3 is a rear view. Fig. at is avertical sectional view on line 44 of Fig. 3.

Q indicates a plate or frame of suitable material, for instance castiron, provided at its front with a keyboard H preferably inclined asbest seen in Fig. 1. This keyboard is provided with perforations hthrough which extend forwardly the arms of angle levers N. These leversare pivoted upon horizontal transverse axle or hinge pins h which passthrough bearing eyes in said levers and through correspondinglyperforated vertical flanges k on the under side of the key board. Thelevers N constitute key levers and are provided at their outer or frontends with indicating disks n as best seen in Figs. 1 and 2. The leversalso have substantially vertical arms '17. which extend downward and areprovided at their lower ends with sockets n in which fit the sphericalends 0 of the punch rods 0. The punch rods are of the various lengthsrequired by the difierent positions of the several keys and extendrearwardly to the horizontally reciprocating punches M to which they aresuitably pivoted by pins m. The punches are mounted and adapted toreciprocate in horizontal bearings b formed in the punch block B, thelatter being mounted upon the face plate Q to which it is firmly securedby screws q. At the rear of the punch block is secured the die 0 havinglongitudinal perforations c opposite the respective punches M and intoand through which the circular punched out portions of the card or paperare delivered, and whence they fall into a suitable receptacle P.Between the die and the punch block is formed a space 0' of sufficientsize and thickness to accommodate the card to be operated upon. Thisspace is preferably formed by casting or planing outa recess in the rearof the punch block as shown in Fig. 1, or by placing between the die andpunch block a piece of sheet metal of thickness adapted to the thicknessof the card.

It will be observed from the description thus far given that if any keylever be depressed, the corresponding punch bar or rod will be forcedlongitudinally backward causing its punch to slide backward in the punchblock, perforate any card which is in position in the space a and passthrough the card into the corresponding perforation c. The constructionof the machine, furthermore, is such that several keys may be struck ordepressed at once, thereby much facilitating and hastening the work ofperforating. The arrangement of the punches for the actuarial work forwhich this machine is primarily designed is preferably as shown in Fig.3, in which will be seen in horizontal rows and vertical columns therear ends of the punches. The levers and punches are returned to theirproper position by springs applied at any convenient or suitable point,for instance, in the construction illustrated such springs are shown atN fitted in sockets N in the key rear faces of the blocks t.

leversand bearing upon the key board (Fig. 1). The key levers are alsopreferably provided with rubber buffers N which are adapted to limit thereturn movement of the keys and punches under the force of the springsN, and also to lessen the noise in operating the machine.

I will now proceed to describe the feed mechanism by which a card to bepunched is by a single simple and quick movement of the operator broughtinto proper position behind the punches and in the space a. G is afinger bar extending across the front of the key board and connected byarms g with pivot bearings g The latter are supported upon theextremities of one of the pins h,which may be madelongerthan the othersforthis purpose. One of the arms g is extended rearwardly beyond itsbearing in the form of a lever arm G, which is provided at its rear endwith a universal joint bearing G in which is mounted the lower end of anupright link F. Thelatter at its upper end fits in a similar universalbearing E mounted upon the end of a horizontal lever arm E, which arm isfurnished with a horizontal hinge bearing E and with a depending orvertical arm E the whole forming an angle lever as seen in Fig.

3. The bearing E is mounted upon a horizontal longitudinal axis or stude carried by a vertical bracket arm R. The latter forms a. part of aframe R which is firmly secured to the punch block B or other suitablesupport. S is a horizontal transverse rod mounted on the frame R andcarrying a sliding cross head T to which latter is connected thevertical lever arm E by means of an anti-friction roller 16 mounted onthe cross head and fitting in a vertical slot e in the said arm. Theframe R is provided with horizontal transverse slots r in which fitblocks t which are secured by screws 25 to the said sliding cross head.On the rear side of the frame R is the card carrier D formed of a thinrod or bar of metal about the thickness of the cards to be used, whichcarrier is secured to the It will be evident from the foregoingdescription that when the finger board or lever G is depressed the cardcarrier will, through the links and levers mentioned, be reciprocatedhorizontally and transversely in or upon the frame R. It will beunderstood that the card carrier is situated in line with the space 0'between the punch block and the die and, if acard be situated in frontof said carrier and the carrier be moved toward said space, is adaptedto force such card into the space and in position to be operated upon bythe desired number of punches. The card thus thrown into position isprevented from going beyond the point to which it is forced by the cardcarrier by means of a friction spring K which is secured to a part ofthe stationary frame of the machine or to the punch block and bears uponthe rear of the latter (Fig. 2). This spring has an upturned end beneathwhich the card to be operated punched.

upon will be forced by the card carrier. After such card has beenpunched it will be forced onward (to the right. in the machineillustrated) under the spring K and e ected from the apparatus by thesucceeding card as the latteris brought into position to be The ejectedcard slides outward upon a ledge Z formed upon the rear face of asupporting and guide plate L. This plate will momentarily sustain thecard 1n an upright position and then permit the card to fall onto thetable or any suitable support upon which the machineis mounted. Thecards thus delivered from the machine will accumulate in a pile in thesameorder in which they are punched. The unperforated cards are storedin a magazine A in proximity to the card carrier, the rear plate or wallof such magazine being formed by the frame B. (Fig. 4). This magazine issecured to said frame and is preferably open .at the top as shown forthe introduction of the cards. The magazine is provided with a followerA which is adapted to move toward and from the card carrier, but ispressed in the former direction by means of spiral springs J, beingguided in its movements by a rearwardly extending rod I adapted to slidein a bearing 1' formed upon the rear of the magazine. Said rod isprovided with a handle or button vlby which the follower may be drawnback for the purpose of introducing the cards. The cards to be punchedare placed to the number of a hundred or more in the magazine A and theforemost card is held firmly against the frame R At each operation ofthe card carrier, caused by the depression of the bar G, the foremostcard is forced into the space behind the punches, and there punched bythe depression of the proper keys, such operation continuing until thecardsin the magazine Aare exhausted. It will be observed that this wholeoperation requires simply two movements on the part of the operator, oneto depress the bar G, and the other to force down the proper number ofkeys. If however, more keys should require to be depressed than can becovered by the fingers of the two hands, which will not ordinarily bethe case, more than one motion may be required for this purpose.

It will be understood that the key board of. the machine illustrated isadapted for a particular kind of life insurance tabulation, and thatthis arrangement of the keys may be varied to suit the requirements ofthe work which is to be performed.

What I claim is- 1. In a perforating machine the combination with theseries of parallel horizontally acting punches, the supporting andguiding punch block, and a die of the key levers having horizontal anddepending arms, and rods connecting the latter arms with the punches,and pivotally secured to the latter substantially as set forth.
